At least, it is a bug with the VDPAU hardware decoding path. And it is
probably not a bug with the VDPAU support in VLC, libavcodec and libvdpau as
they work with other hardware. That leaves either the userspace or kernel
space parts of the Nouveau driver as the most likely culprits.
Generally speaking, using VDPAU with anything other than an NVIDIA GPU and the
NVIDIA binary drivers is not recommendable. It seems that just about all VDPAU
drivers other than NVIDIA's are somehow broken.
